LaBeouf, along with musical collaborators Nastja Sade Rönkkö and Luke Turner, are livestreaming their experience for 24 hours in a cramped elevator in Oxford, England. The trio started the project Friday morning — using the hashtag #ELEVATE — and will end it at 9 a.m. local time Saturday.

LaBeouf is allowed to take bathroom breaks, and will also step outside temporarily to host a talk Friday night at the debating society at Oxford University.

Visitors have been sharing their experiences on the elevator with the 29-year-old "Transformers" star, who is answering questions and taking selfies.

Shia does not like Harrison Ford, Donald Trump. Loves Bernie. “It would be great if he were President.” #ELEVATE
